Reference: curve controller function takes the following arguments:curve:object name–The name of object in 3ds Maxdim:1,2 or 3— set the controller on specific dimension.feedback:transform/position/rotation –function returns transform matrix, position in point3 value and rotation in EulerAngles value localOffset:offset value— offset the index value and shifts item along the path.endOffset:offset value— move all items away from the last point of the path.startOffset:offset value— move all items away from the first point of the pathmode :1 or 2— set the controller in absolute mode (1) or relative (2)order:1 to 9— choose the order of rotation (items in drop down menu) works only when feedback is set to rotation
